28 nm GCN (Graphic Core Next) ArchitectureThe new and 28nm GCN Architecture with more efficient process technology puts more transistors in less space, enabling a dramatic increase in Processing Power. Crank the settings, devastate your enemies and bear witness to absurdly high frame rates with AMD Radeon HD7000 series graphics card-DirectX 11 has never looked this good. Maximum setting and crazy performance shouldn’t be a compromise. The AMD Radeon HD7900 Series with the new 28 nm GCN Architecture assures that it’s not.

PCI Express 3.0PCI-Express 3.0 delivers double the bandwidth per lane of PCIe Gen 2 for faster GPU (GPU communication-up to 16GB/sec in each direction), maximizing the performance from your GPU when paired with the latest platforms.

AMD HD3D TechnologyEnjoy the most immersive experience possible with full support for High Definition Stereoscopic 3D, a technique that presents 2D images (movies, games, photos) in a format that creates the illusion of three-dimensional depth when using compatible 3D displays / glasses / software.

Best Microsoft DirectX11 SupportThe tessellation performance on AMD Radeon HD7000 is up to 2X faster than the previous generation, and DirectCompute performance is also faster to accelerate advanced post-processing, filtering, and anti-aliasing techniques. Direct X11 games has never looked this good.
